Everybody Got A Gris-Gris

Posted by mattusmaximus on October 17, 2011

I just had a guest post published over at the James Randi Educational Foundation’s Swift blog, and I thought it worth sharing. Take a look…

If you’re like me, then when you became a more open and active skeptic (what I like to call a “coming out” skeptic) you may have made the mistake of thinking that you were going to make yourself into the best skeptic ever.  That is, you may have decided that you were going to aspire to being a really, really good skeptic and critical thinker on pretty much everything.  I recall my eager embracing of this kind of “hyper-skeptical” attitude, back when I was a newly minted “out of the closet” skeptic.

But, as I have matured, I have adopted a more informed, nuanced, and realistic view of skepticism, both on a personal as well as a broader level.  I have come to the gradual realization that while wishing to be “a good skeptic” in all areas, from the nuances of the alt-med vs. science-based medicine wars to issues related to various religious claims, is a laudable goal, but at the end of the day it is kind of unrealistic.  There simply aren’t enough hours in the day to comb through all the pseudoscientific, conspiracy-mongering, and woo-oriented claims out there and be totally prepared for them all.

This is why having a community of skeptics is so important: we each bring our own areas of expertise and activism to the larger group.  I, for one, tend to focus on issues related to what I call physics-woo and topics related to pseudoscience and education (specifically areas such as the creationism-evolution issue).  That way we can take the time to hunker down and focus upon a specific set of skeptical topics, while relying on the rest of our skeptical colleagues to cover other areas.

However, there is another reason why being plugged into a broader skeptical community is a good thing: because we are all human, and as such, despite our skeptical leanings we all have some aspect to our lives on which we are decidedly non-skeptical.  As the magician Penn Jillette once summed it up: “Everybody got a gris-gris.”  By this he meant that we all have some kind of gris-gris: a belief or superstition or viewpoint that is not supported by any kind of rational or skeptical analysis.  And, many times, these gris-gris are things that are very important to us, yet we may not even think of it as such, and we can behave in decidedly irrational ways when confronted with the possibility that our gris-gris is just another silly belief unsupported by evidence. …

Media Fail & Lotteries

Posted by mattusmaximus on January 22, 2011

This past December 17th, I saw a headline in my local paper which stunned me with the level of irresponsibility it displayed.  Back then the Powerball lottery was getting a lot of attention because the jackpot was up to a potential $25 million, and when such numbers start getting thrown around, people’s critical thinking skills go right out the window.  And it doesn’t help when the media joins the chorus of unreason…

First, there is the fallacy that when the jackpots are high, more people play because they “feel lucky that they’re going to win the BIG one!”  Of course, when more people play the lottery it actually decreases the odds that any specific person will win, yet this doesn’t stop the gullible from scarfing up the lottery tickets.

Then, there’s this horrible headline:

Wanna win Powerball? Try these numbers

For 13 years, a red ball with the number “20” printed on it has been whirling around with its numerical counterparts in an enclosed Powerball kettle waiting to potentially make someone a millionaire. That No. 20 red ball has made its way out of the kettle 49 times, the most of any of the numbered balls. No. 20 also is the second most common number on the five white balls that are selected in each Powerball drawing as well, behind 26 and ahead of 32, 16 and 42, a Daily Herald analysis of the numbers shows. …

This headline and the leading paragraphs of the article play directly into the gambler’s fallacy of “lucky numbers” – in reality there are no more or less “lucky” numbers.  In fact, the past performance of the lottery is in no way, shape, or form a predictor of the next random drawing of numbers.  The article cited above actually does attempt to be at least marginally responsible by interviewing a mathematician, though their discussion is buried in the article…

… While some gamblers may see that information as an edge, mathematicians and oddsmakers say it’s all just luck.

“The numbers and the pingpong balls have no memory,” said Jeff Bergen, a mathematics professor at DePaul University. “So whether a given number has come up once or twice or 10 times or never, it is no more or less likely to come up today than any other number.” …

Exactly.  Unfortunately, the “news” article quickly followed up the math professor’s advice with some anecdotes from believers in these supposed lucky numbers.  So how did the Powerball drawing in question go?  Here were the results of the Dec. 18th Powerball drawing:

04-11-19-33-43 and 14 as the Powerball

And remember, the so-called “lucky numbers” referenced in the article were 16, 20, 26, 32, 42, and 20 for the Powerball.  Not a single one of these numbers appeared in the drawing – NOT… ONE. So much for “lucky numbers.”
So how should one win the lottery?  Simple: by not playing it at all.  To sum up the best way of dealing with this foolishness, I like this comment which appeared in response to the article:
You have much better chances of most things than of winning the lottery–getting struck by lightning, dying in a plane or car crash, etc. The odds are astronomically low of winning the big prize. Invest that money instead, and you’d end up with far more in the long-term, even with the low interest rates.
As for the “news” paper which so irresponsibly reported this article, I can only say one thing…

Draw Muhammad Day: A Defense of Free Inquiry & Expression

Posted by mattusmaximus on May 3, 2010

Lately the news of threats against Matt Stone & Trey Parker, the creators of South Park, for displaying a likeness of the Muslim prophet Muhammad have gotten a lot of press.  And I’ve decided to post my views on the matter.  Usually, mostly because I am surrounded by it, when I talk about religious woo & stupidity I am referring to Christian fundamentalism. But this post is going to be dedicated to taking on what is becoming increasingly obvious to me – the creeping influence of politically-correct arguments made on behalf of fundamentalist Islam with the intention of shutting down any & all criticism and/or free inquiry regarding that religion.  I have a pithy two word response to this notion: F%@k that!

Bottom line: when dealing with fundamentalist religion, especially when faced with a brand of fundamentalism so whacked out that it preaches violence against critics (such as the modern-day radical “Islamists”), in my view you have but one of two choices:

1. Cater to the fundamentalists and watch your liberty slowly slip away, or

2. embrace your fundamental freedoms – such as the freedom of inquiry & expression.  This means you’re going to have a fight on your hands.

Guess which one I choose?

I won’t go into a long screed on how I think the South Park guys are just totally badass for having the guts to take on, well, everyone’s goofy beliefs and poke fun at them (even hardcore atheists such as Richard Dawkins).  I also won’t waste time pillorying the weak-kneed panzies over at Comedy Central for capitulating to a bunch of idiotic radical Muslims who should be, if anything, basically ignored.  I won’t even take more than this line to point out the obvious: if you cannot handle your religious beliefs being questioned and, sometimes, being ridiculed by non-believers, then you have deeper issues that need to be addressed and should go live on an island in the middle of nowhere.

In the spirit of fighting back against this creeping notion that “we cannot criticize the religious beliefs or take a chance on ‘offending’ anyone who holds such belief”, specifically regarding Islam, I want to pass along a really great idea I stumbled upon a few days back: Draw Muhammad Day (DMD).

May 20th, 2010, will mark the first DMD – despite the fact that the cartoonist who originally came up with the idea decided to back out.  It’ll happen regardless, because now the whole idea of DMD has gone completely viral on the Internet.  No doubt that some people will take this opportunity to draw the prophet Muhammad in a less-than-glamorous light, such as outlined by this image…

… and I’m sure that some jerks will come up with many much more offensive images than that which are specifically designed to offend.  Fine by me – being a jerk is well within the bounds of free speech; but, in my view, being a jerk isn’t what DMD should be about… it should be about promoting free inquiry/expression.  What is bothersome to me, more than anything, is the notion among some of these radical Muslims that any depiction of Muhammad is somehow offensive, and that to spare them from “offense” everyone else (including many moderate Muslims) should cater to their whims.  It is also worth noting that the image of Muhammad has been depicted countless times over the course of history, even by various Muslim cultures – this is an important detail the radicals would rather have you not know!
